Which of the points shown below are on the line given by the equation y = x + 3​

Answer:

Step-by-step explanation:

To find the vertex of this parabola, "complete the square:"  Rewrite y = 4x2 - 12x + 9 in the form y = 4(x - h)^2 + k:

y = 4x^2 - 12x + 9  =>  y = 4(x^2 - 3x) + 9.

Now complete the square of x^2 - 3x:  Take half of -3 and square the result, obtaining (-3/2)^2, or 9/4.  Add 9/4 to x^2 - 3x and then subtract 9/4 from the result:  We get x^2 - 3x + 9/4 - 9/4.  Substitute this result back into

y = 4(x^2 - 3x) + 9:  y = 4(x^2 - 3x + 9/4 - 9/4) + 9

and then rewrite the perfect square x^2 - 3 + 9/4 as the square of a binomial:

                                 y = 4(x - 3/2)^2 - 9/4) + 9.  This simplifies to:

                                 y = 4(x - 3/2)^2 + 0.

Thus, the vertex is at            (3/2, 0) and the axis of symmetry is x = 3/2.  This agrees with Answer B.

Answer:

10

Step-by-step explanation:

[tex]11430\cdot 14 = 160020[/tex] ounces

[tex]160020\div 16=10001.25\approx 10[/tex] tons.

Hope this helps!

The required weight that the truck carried in ton is 5.

In the counting or finding data problem we first calculate the value of unity element then further add or multiply the next ones

Here we have given truck carry

11,430 bottles

If each bottle weight = 14 ounce

Therefore total weight of 11,430 bottles is = 11,430x14 = 160020 ounce

Also we have

1 ton = 32000 ounce

Or 1 ounce = [tex]\frac{1}{32000}[/tex] ton

Therefore the required weight in ton of total weight 160020 ounce is

= [tex]\frac{160020}{32000}[/tex]

= 5

This is the conclusion to the answer.

Step-by-step explanation:

Answer:

61 : 60

Step-by-step explanation:

Well to make a ratio, you just have to have David time : Mark time

So if you convert Mark's time into minutes, it is 60 minutes

61 : 60

That's the simplest form.

Answer:

ratio of David's time to Mark's time = 61/60 = 61:60 = 61 to 60

Step-by-step explanation:

A ratio is a way of comparing numbers by dividing one number by the other. In order to write a ratio, both numbers have to be in the same units.

David takes 61 minutes to do a task.

Mark 1 hour to do the same task. 1 hour = 60 minutes.

You are comparing David's time to Mark's time.

The ratio of David's time to Mark's time is 61 minutes to 60 minutes.

ratio of David's time to Mark's time = 61/60 = 61:60 = 61 to 60

Answer:

351

Step-by-step explanation:

Complete question :

Vanilla= 36

Chocolate=21

Strawberry=24

Chocolate Chip=39

SOLUTION:

39 chocolate chip to 200 students = x chocolate chip to 1800 students

39/200 = x / 1800

Solving for 'x'

(200)(x) = (39)(1800)

200x = 70200

x = 70200/200

x = 351

OR

39 out of 200 picked chocolate chip

therefore, 39/200 = 0.195 = 19.5%  ( 32.5% chose chocolate chip)

19.5% of 1800 = 0.195(1800) = 351 students

Step-by-step explanation:

Answer:

Each pizza costs $12.

Each drink costs $2.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of each pizza.

y is the cost of each drinks.

The Talbot family got 2 pizzas and 4 drinks for $32.

This means that [tex]2x + 4y = 32[/tex]

The Martinez family got 3 pizzas and 8 drinks for $52.

This means that [tex]3x + 8y = 52[/tex]

Using the addition method, multiplying the first equation by -2.

-4x - 8y = -64

3x + 8y = 52

-4x + 3x - 8y + 8y = -64 + 52

-x = -12

x = 12

Each pizza costs $12.

2x + 4y = 32

2x + 4y = 32

4y = 32 - 2x

4y = 32 - 2*12

4y = 8

y = 2

Each drink costs $2.

To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (L), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

To find the total surface area of a figure, we need to add all the areas of every surface and add them.

What is the surface are?

The surface area of a figure is the total area of the outside of the figure.

If the surface area of a particular figure is just only one type (ex: sphere), then the calculation of the surface area will be easier.

If the surface of a figure consists of different types of geometrical figure(ex: cone), then we need to find the area of each and then add them.

Step-by-step explanation:

P(a|b)= this mean the probability that a happens given that you already know b has occurred.

So for this P(work|senior) is the probability you will pick someone who works give you know they work. So you look for the over lap between seniors and work in the table and divide it by the number of seniors.

In this case:

P(Work | senior)= 5/(25+5+5) = 5/35 = 1/7

Answer:

A) Total amount to be paid = Birr 8,560

B) Amount of VAT liable to the dealer = Birr 520

Step-by-step explanation:

The tax on bought commodity and the tax on sold commodity isn't provided but in some places, these values are 7% and 9% respectively. So, these are the values that will be used for this question.

Note that these values vary from country to country and the value missing from this question will not change how the question is solved; the question will still be solved in a similar manner, only the parameters will vary.

A) The dealer bought Birr 8000 at 7% tax.

Total amount to be paid = cost price (1 + r%)

r = 7% = 0.07

Total amount to be paid = 8000 × 1.07 = Birr 8,560

B) To find the VAT, it is the difference between the tax paid when the good was bought and the tax put on it after it was sold.

Tax paid when the shoes were bought = 7% of cost price = 7% × 8,000 = Birr 560

Tax paid when the shoes were sold = 9% of selling price = 9% × 12,000 = Birr 1,080

VAT = tax recovered on sale - Tax paid on purchase

VAT = 1080 - 560 = Birr 520

Answer:

Option B. y = 14x - 3.5

Number of wins for the team will be 24.5

Step-by-step explanation:

Since line of best fit passes through two points (0.25, 0) and (0.75, 7)

Let the equation of the line of best fit is, y - y' = m(x - x') + c

Here 'm' = Slope of the line

              = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

              = [tex]\frac{7-0}{0.75-0.25}[/tex]

              = [tex]\frac{7}{0.5}[/tex]

          m = 14

Equation of the line of best fit passing through a point (0.25, 0) will be

y - 0 = 14(x - 0.25)

y = 14x - 3.5 [Option B]

Now number of wins for a team that scores 2 goals per match will be,

For x = 2

y = 14x - 3.5

y = 14×2 - 3.5

  = 28 - 3.5

  = 24.5 wins

Therefore, number of wins for the team will be 24.5
